- EJECTOR MECHANISM.

Specification of Letters Patent.

Patented Apr. 18, 1916.

Application filed August 9, 1915. Serial No. 44,519.

Be it known that I, DAVID PETRI-PAL- MEDO, a citizen of the United States, residing at Bridgeport, in the county of Fairfield and State of Connecticut, have invented a certain new and useful Improvement in Ejector Mechanism, of which the following isva full, clear, and exact description.

Type bar casting machines, in which the type bars are cast in a mold slot, one edge of which is closed by a line of assembled matrices, are so organized that, after a type bar has been cast, an ejector is caused to push the type bar out of the mold slot and between the trimming knives. Such machines are organized to employ molds whose slots are of various widths and of various lengths, and also molds in some of which the slot is unobstructed, while, in others the slot contains cores substantially as shown in Letters Patent No. 1,078,930.

This invention is an ejector which may be used to eject solid slugs from unobstructed mold slots, and also to eject recessed slugs from such cored molds without injuring said recessed slugs.

The invention consists in the construction and combination of parts shown in the drawings, hereinafter described, and pointed out definitely in the appended claims.

In the drawing, Figure 1 is a perspective view of an ejector slide which embodies the present invention, which slide is shown bottom side up; Fig. 2 is a transverse sectional view in the plane of line 22 on Fig. 1; and Fig. 3 is a longitudinal section of said ejector slide.

These ejectors must be constructed so as to be capable of being mounted in guide-' ways by which they are supported and guided so that as they are moved forward and backward, they must move in right lines. The body part 10 of the slide shown in the drawing has parallel sides. These are at such distance apart and the body is of such thickness that said body may be mounted in such guideways. Integral with and projecting forward from the front end of the body is the ejector blade 12, whose upper face is in the same plane as the upper face of the body. This blade is, however, thinner than the body, and therefore there is formed, at the juncture between the body rality of parallel longitudinal grooves 15 Y are formed.

16 represents T-bars whose length corresponds with the length of the blade. The edge of the web portion 16 of each T-bar is fitted into one of the grooves 15 andthere secured, as for example, by small rivets 19, which, as will be understood, are subjected to very little strain when the ejector is in use. These bars are parallel with one another and with the side edges of the body. The lower surfaces of their T-shaped heads are in the same plane with one another, which plane is parallel with the plane of the upper surface of the blade to which they are attached. The distance between these two planes should be just a little less than the width of the mold slot with which the ejector is to cooperate. The rear ends of said T-bars abut against the ledge 14, which therefore, takes the thrust incident to push ing a type bar out of a mold slot. But the height of these bars is or may be greater than the thickness of the body 10, as for example, when the width of the mold slot is considerably greater than the thickness of the body. When this is the case the banking plate 17 is secured by screws or other suitable means to the lower face of the body with its front edge in the same plane as that of the ledge 14. Wherefore this banking plate engages the.rear ends of the T-shaped heads of the T-bars, and takes some of the thrust incident to the ejection of a slug.

The described ejector may be used to eject slugs from molds whose slots contain cores, as shown in the above mentioned prior patent, and also for mold slots which do not contain cores. In either event, the slug will be pushed in a straight line out of the mold slot and between trimming knives, and that without injury to the more or less soft base of said slug. Moreover, the construction is such that to construct a set of ejectors, for use with the various molds which may be put into a machine, requires only that the width of the blade be varied, that the number of T-bars be correspondingly varied, and that the height of the web of the T-bars be varied to suit the requirements of the particular cases. Therefore the particular ma-.

Having described my invention, I Vclaimi .1. An e ector for line casting machines comprising a body having parallel sides, a

forwardly projecting blade of suitable width, and a plurality of T-bars rigid with the depressed face of said blade and parallel with one another and with the sides of said'body. V

2. An ejector for line casting machines comprising a body having parallel sides, a forwardly projecting blade of suitable width and of'less thickness than said body and whose upper face is in the same plane as the upper face of said body, and a plurality of T-bars projecting downward from the depressed face of said blade and connected to said blade, which T-bars are parallel with oneanother and with the sides of said body and are of the same length as said blade, and have their rear ends in contact with the transverse ledge formed at the juncture of said body and blade.

3. An ejector for line casting machines comprising a body having parallel sides, a forwardly projecting blade of less thiclmess than said body which blade hasiin its depressed surface a series of parallel grooves, T-bars whose length corresponds with the length of said blade, which-T-bars have rthe edges of their webs secured iii said grooves and have their rear ends in "contactwith'the transverse ledge formed at the juncture of the said body and blade.

at. An ejector for line castingmachines comprising abody having parallel sides, a

' forwardly projecting blade of less thickness versely extending banking plate secured to said body with its front edge in contact with the'rear ends of said T-bars' In testimony whereof, I hereunto affix my signature in the presence of two witnesses.
